More than 900 people have now been confirmed dead and over 3000 are still missing following a glacier collapse on the Nepal-Tibet border.

More than 800 people are now known to have died and more than 3000 are still missing following a glacier collapse on the border between Nepal and Tibet on Wednesday 26 August 2026. The incident was first recorded as a Magnitude 4.4 Earthquake by the United States Geological Survey at 2.52 am GMT, which is 8.37 am in Nepal and 10.52 am in Tibet (Tibet has been part of China since the 1950s, and China uses a single time-zone for all its territory, leading to a two-and-a-half hour time gap between Tibet and Nepal, despite their having a similar longitude), a figure which was revised to a Magnitude 5.2 event shortly after. Seven minutes after this a flash flood and debris flow hit the Gyirong Port border crossing between Nepal and Tibet, before passing along the Lhende Khola River Valley in Nepal and into the Trishuli River system.

This event was initially interpreted as an Earthquake-induced glacier collapse, probably caused by a glacier shattering and releasing a melt-lake which had built up behind it. Such events are the most common form of glacier collapse, and are particularly associated with warming global temperatures. Essentially, glaciers begin to melt behind their leading edge, with the amount of ice in front of the growing lake slowly decreasing till the whole edifice collapses. However satellite images taken in the days before the collapse revealed no such lake, and it is now thought that a chunk of glacier with an area of about 200 000 m², and a volume of 1-2 million m³, broke off a glacier at an altitude of between 5200  m and 5400 m above sealevel, then dropped vertically about 1200 m into the valley below. This impact caused the event which the United States Geological Survey interpreted as an Earthquake.

Approximately seven minutes after this initial collapse, the Gyirong Port Border Crossing was hit by a flood and debris flow 80 m high, travelling at approximately 180 km per hour (50 m per second). This remarkable velocity was driven largely by the steep nature of the high mountain valleys, with the Gyirong Port border crossing being approximately 3000 m lower than the initial impact point of the falling glacier. The debris flow continued down the valley for approximately 100 km, sweeping away 41 bridges and 42 km of road, as well as the Gyirong Port border crossing in Tibet and the corresponding Rasuwagadhi Customs Office in Nepal, as well as numerous homes and other buildings, and causing significant damage to six hydroelectric projects in Nepal. Bodies of victims of this flood event have been found as far away as Uttar Pradesh in northern India, more than 250 km from the initial glacier collapse event.

Glacier collapses are a part of the natural cycle of events within the Himalayas. The mountains here are not static, but are actively growing as the northward movement of the Indian Plate pushes up the overlying Eurasian plate. This means that glaciers which sit upon these mountains are slowly raised to ever higher altitudes, while at the same time becoming ever more steeply inclined. Eventually, this situation becomes unstable, and gravity overcomes the ability of the ice to stick to the underlying rocks, causing sections of glacier to collapse down the sides of the mountains.

This situation is made significantly worse by rising global temperatures, with the Himalayan region warming at twice the global average, which lead to higher rates of melting on glaciers in the Himalayas. The problem here is not just that the ice melts, but that when it does the water tends to percolate downward through any cracks or holes in the glacier surface, eventually pooling on the underside of the glacier. This creates a layer of liquid water over which the glacier can flow, which is the natural way in which glaciers move in lowland areas, but can lead to catastrophic consequences on high, steeply inclined glaciers.

This warming does not just threaten glaciers in these regions; many of the highest mountains are effectively rubble piles held together by ice and frozen soil (permafrost). As the Himalayas warm this ice can thaw, leading to parts of mountains breaking away, leading to more and larger landslides and rockfalls in an area where these are already a major threat to both lives and infrastructure. 

Rescue efforts following the 26 August event have been greatly impacted by the loss of roads and bridges, as well as the large amounts of mud and silt left behind by the floods. Rescue workers have often had to wade through deep mud to reach communities cut off by the floods, with other communities only accessible by helicopter.

Concerns were raised about a second flood hitting the area on Thursday 27 August, after Chinese authorities discovered a barrier lake which had formed behind debris deposited at the confluence of the Chhochen Khola and Purepu Tsangpo rivers in Tibet. At the time, there was an estimated three million cubic metres of water in this lake, which had begun to overtop the barrier, leading to fears of an imminent collapse. However, this lake subsequently drained away naturally without Human interference, and had largely disappeared by Sunday 30 August.

At least eight dead following landslide in Chongqing, China.

Eight people are known to have died and thirty four people are missing following a landslide in Pengshui County in the Chongqing Municipality of China on Friday 17 July 2026. The incident took place at about 9.10 am local time, and caused about 18 000 m³ of rock and soil (including boulders up to 3000 m³) to shift, burying ten residential buildings. Around 1100 people have been evacuated from the area around the incident, with water, electricity, and gas supplies cut off from buildings within 1 km of the landslide as a precaution. Around 800 rescue workers have been deployed to the site, with ten people dug out of the rubble so far, two of whom are described as being in a serious condition in hospital.

The incident happened during heavy rains associated with the summer monsoon, with 192 mm of rain falling overnight before the landslide. Landslides are a common problem after severe weather events, as excess pore water pressure can overcome cohesion in soil and sediments, allowing them to flow like liquids. Approximately 90% of all landslides are caused by heavy rainfall. 

However, local authorities have also noted that the area where the landslide occurred is noted for its 'unpredictable' geology, with the Wujiang River cutting through uplifted an karst (eroded limestone) terrain with steep-sided valleys and many cliffs prone to major rockfalls.

Chongqing has a subtropical climate with a rainy season running from mid April to mid October, though rain falls year round. Rainfall is typically highest in June when the area often receives over 200 mm of rainfall. July is drier, but typically still has over 180 mm of rain. Prior to Human settlement, the area was largely covered by forests, with a cool temperate deciduous forest during the last Pleistocene glaciation being replaced by a broad-leafed evergreen forest in the Holocene. However, Chongquing is now one of the most densely populated areas of China, which has led to the loss of much of this forest, the roots of which would have helped to bind soils on steep-sided slopes, leaving areas such as the Wujiang River valleys exposed to heightened landslide risks, and often heavily populated.

Bryozoans from the Early Cambrian Cambrian Xiannüdong Formation of Shaanxi Province, China.

Molecular clock studies have suggested that the Phylum Bryozoa, or Moss Animals, first appeared in the Early Cambrian, which is consistent with the appearance of nearly all other Animal phyla at this time. However, for a long time the earliest known fossil Bryozoans came from the Early Ordovician, at which point six of the eight known orders of Bryozoans appear abruptly. Several putative Cambrian Bryozoan fossils, such as Pywackia, Archaeotrypa, and Marcusodictyon, were described, but none of these was universally accepted as a Bryozoan. In 2021 a more plausible Brozoan, Protomelission gatehousei, was described from the Early Cambrian of Australia and South China. In this it was possible to identify several Brozoan traits, including monomorphic zooid capsules, modular construction, organic composition, and a simple linear budding growth geometry, leading to the conclusion that this was probably a stem-group Bryozoan.

(i) Enlarged view of three adjacent zooids. Note the dome shape of the distal part of frontal wall (tailed arrows), and almost circular orifice of zooid. Abbreviations: B, basal wall; F, frontal wall. Zhang et al. (2021).

However, while Protomelission gatehousei shows enough Bryozoan-like features that most palaeontologists have accepted it to be at least a stem group Bryozoan, the specimens used to describe the species lacked the definitive Bryozoan soft-tissue anatomy and diagnostic skeletal microstructure which would be necessary for complete conformation, leaving the identity of these fossils open to challenge.

In a paper published in the journal Nature on 3 June 2026, Baopeng Song (宋宝鹏) and Zhifei Zhang (张志飞) of the Department of Geology at Northwest University, Luke Strotz, also of the Department of Geology at Northwest University and also of the Department of Earth Sciences at Utrecht University, Timothy Topper, again of the Department of Geology at Northwest University, and of the Department of Palaeobiology at the Swedish Museum of Natural History, Andrej Ernst of the Institut für Geologie at Universität Hamburg, Zhiliang Zhang of the Department of Geology at Northwest University, and the Institut für Geologie at Universität Hamburg, Mei Luo (罗梅), again of the Department of Geology at Northwest University, Lars Holmer, again of the Department of Geology at Northwest University, and of the Department of Earth Sciences at Uppsala University, Yue Liang (梁悦), Yazhou Hu (胡亚洲), Caibin Zhang (张彩彬), and Yanlong Chen (陈延龙), all of the Department of Geology at Northwest University, and Glenn Brock, once again of the Department of Geology at Northwest University, and of the School of Natural Sciences at Macquarie University, describe new specimens of Protomelission gatehousei from the Early Cambrian Xiannüdong Formation of southern Shaanxi Province, China, as well as a second new species of Bryozoan from the same formation.

Notably, these fossils preserve soft-tissue features in exceptional fidelity, including internal moulds of membranous sacs in the zooid chambers, which allow the unequivocal placement of these taxa within the Phylum Bryozoa. The presence of two separate Bryozoan taxa within these Early Cambrian deposits pushes the origin of the group still earlier, confirming that this group appeared during the Cambrian explosion.

Note that the secondary phosphate coating of the aperture is partially stripped away.

These new specimens show Protomelission gatehousei as forming upright colonies with two curved lamellar sheets of zooids back-to-back, with the largest colonies being 1-2 mm in width and about 3 mm high, tapering towards their tip. Each of these lamellae has six-to-eight rows of zooids, with budding originating from a planar mesotheca.

(f) Protective shields developed in an extant Cheilostome Bryozoan, Valdemunitella sp. photographed by Dennis Gordon (Wellington). Song et al. (2026).

The new species described is named Dayingomelission hexaclitia, where 'Dayingomelission' means 'honeycomb from Daying' and 'hexaclitia' means 'six slopes' in reference to the sloped, hexagonal apertures of its autozooids. Colonies of Dayingomelission hexaclitia form a sheet-like grown covering the substrate. This sheet is interpreted as having spread by linear branching, with a single row of zooids diverging to form two new rows. Each autozooid is hexagonal and box-like, between 200 µm to 400 µm in diameter, and separated from its neighbours by a double-walled structure. All vertical walls show this double-walled structure, while the basal wall is planar, sometimes showing a slight curvature.

Both species have hexagonal zooids with a box-shaped profile and a non-porous phosphatized or silicified skeleton. These are more-or-less uniform in size, and angled at 30-75° to the median lamina or basal exterior wall. They have preserved phosphatized internal structures interpreted as membranous sacks, the outer end of which comprises an elliptical orifice surrounded by an undulating fold. These are made up of densely packed circular and longitudinal fibres interpreted as annular and longitudinal muscles. Longitudinally aligned cylindrical structures, possibly representing protective shields or a broad operculum are present in some specimens. In others sac is attached to the cystid wall in the inner part of the zooid cell.

Both Protomelission gatehousei and Dayingomelission hexaclitia show most of the key features associated with Palaeozoic Bryozoans, including  aspects of their colony morphology, their skeletal architecture,  the presence of soft-tissue structures such as membranous sacs, as well as annular and longitudinal musculature. Notably they contain a number of features associated with the Class Stenolaemata, including styles and  a free-walled colony organisation, which would make both species crown-group Brozoans. This makes it more likely that they were biomineralized in life, although it is impossible to determine the initial composition of their skeletons. Brozoans are known to have undergone a number of independent biomineralization events, with a molecular clock analysis indicating that the first of these was likely to have happened in the Early Cambrian. These results also imply that the common ancestor of the organic￾walled Gymnolaemata and the mineralized Stenolaemata probably originated in the early Cambrian (Terreneuvian) or even perhaps in the Ediacaran Period.

Node values are Bayesian posterior probability support values. Coloured areas indicate the three taxonomic classes that comprise the Bryozoa along with outgroups, with Protomelission and Dayingomelission belonging to Stenolaemata. Song et al. (2026).

The presence of two species of Bryozoan in the Early Cambrian Xiannüdong Formation of Shaanxi Province, as well as one of these species being present in the lower Wirrealpa Limestone of South Australia makes it likely that Bryazoans had already diversified and become widespread in the Early Cambrian. This lends support to the idea that the tentative mineralised Bryomorphs from the Lower Cambrian of Nevada recently described by Pruss et al. (2022) are also Bryozoans, and that Moss Animals were therefore widespread in shallow Cambrian seas, particularly Archaeocyath reef-associated carbonate platform settings.

Explosion at coal mine in Shanxi Province, China, kills at least 82 people.

At least 82 miners have died in an explosion at a coal mine in Shanxi Province, China, on Saturday 23 May 2026. The incident happened at Liushenyu Coal Mine in Qinyuan County slightly before 7.30 pm local time at which 247 workers were below ground. The majority of those have now been evacuated, with 128 people being treated in hospital, two of whom are described as being in a serious condition and two more still missing.

Survivors of the incident report seeing a dust plume rather than hearing an explosion, accompanied by a strong sulphurous smell and then many people blacking out. The majority of those killed and injured are reported to have been affected by gas poisoning. 

Coal is formed when buried organic material, principally wood, in heated and pressurised, forcing off hydrogen and oxygen (i.e. water) and leaving more-or-less pure carbon. Methane is formed by the decay of organic material within the coal. There is typically little pore-space within coal, but the methane can be trapped in a liquid form under pressure. Some countries have started to extract this gas as a fuel in its own right. When this pressure is released suddenly, as by mining activity, then the methane turns back to a gas, expanding rapidly causing, an explosion. This is a bit like the pressure being released on a carbonated drink; the term 'explosion' does not necessarily imply fire in this context, although as methane is flammable this is quite likely.

Chinese authorities have dispatched six specialist rescue teams to the site, with a total of 345 personnel and a number of specialist robots capable of entering mines inaccessible to Human rescuers. These have found flooding in the area where the explosion took place, as well as high carbon monoxide levels throughout much of the mine. They have also found that the blueprints of the mine provided by its owners, the Tongzhou Group, do not match the actual layout. 

The mine's management, which have previously been given penalties for administrative failures twice in 2025, are now under investigation for a number of breaches, including developing new coal faces which were not on plans, falsification of health and safety documentation, poor employee records, and illegal uses of subcontractors. Four other mines operated by the Tongzhou Group have been temporarily closed, and mines across Shanxi Province are being subjected to emergency inspections.

Historically, the Chinese coal industry has been beset by safety problems, at least in part due to the rapid expansion of the industry to fuel the country's industrialisation. In the past two decades a major drive towards introducing safety measures combined with a switch away from coal towards renewable sources of energy has reduced the number of such incidents. However, coal is still a major industry, with about a quarter of the coal extracted in China coming from Shanxi Province, and safety clearly still remains a problem.
